Frequently Asked Questions

How do I start using Qizx ?

The documentation contains a chapter titled "Getting Started". Qizx is a class library that comes with two applications: Qizx Studio a graphic interface, and a command-line tool to run scripts.

What is the difference between Qizx/open and Qizx ?

Qizx/open is essentially a cut down version of Qizx, it has neither persistent document storage nor indexing. But it is fully open-source (under Mozilla Public License), while Qizx is not. Of course a large portion of Qizx's source code is the same as Qizx/open. There is a comparison matrix here.

How do you pronounce Qizx ? What does it mean ?

Pronounce "Quiz X". It was originally an acronym for Querying Indexed Compressed(=Z) XML.

May I use Qizx Free Engine in a corporate application ?

Yes, the Free Engine may be used in an in-house application, even in production. Remember however that the databases handled by Qizx Free Engine are limited to about one gigabyte of XML in size, and that you have no support from XMLmind. For more details, please consult the license here.

May I embed Qizx Free Engine in a commercial product ?

No. You may not redistribute Free Engine in any way. Please consult the license here.

How can I use to Qizx from my .Net application (or from C/C++, PHP, Python, etc)?

Qizx is an embeddable engine written in Java. You can use it to implement a J2EE Web Application callable from any web client.

Qizx Server (from version 4.0) is a HTTP-based server extension for Qizx. It supports two simple extensible protocols that can be used from any client application supporting client HTTP requests.

In Qizx Milestone 1, there was a functionality for retrieving data from SQL relational databases (called SQL Connectivity). Why is it no more available ?

This functionality is under redesign. The extension in M1 and Qizx/open was a rough-and-ready solution. The new version will be more evolved, with some automatic translation from XML Query to SQL.
